Over the course of several years, the telecommunications industry has seen continuous growth, together with changes in technology and consumer behaviour, and the Company first recognizing the opportunities for the installation of telecommunications towers in 1999. Currently, the Company provides design, purchasing and installation services for telecommunication systems, both mobile telephone signal systems and complete basic telephone systems, by a professional team of engineers with over 10 years experience. When taking on an installation project, the Company will study and design a steel-framed tower, using one of several designs through a computer program that allows changes to be made to the proportions, form, height and weight of the mast, in order meet the customers requirements and for the efficient transmission of mobile signals, and also produces a design ready for the communication equipment such as the signal transmission systems of different mobile phone operators, power systems and electric wiring systems. Next, the Company will hire a contractor to prepare the construction area, lay the foundations, construct the steel frame and install the communication equipment, with the Companys engineers overseeing construction, connecting the signal and testing that the quality of the work meets the customers specifications and is handed over as scheduled. In addition, the Company provides after-sales services with a 1-year warranty period to ensure customer satisfaction and confidence in the quality of the work.
